Admissible reversing and extended symmetries for bijective substitutions
(Springer, 2023)
In this paper, we deal with reversing and extended symmetries of subshifts generated by bijective substitutions. We survey some general algebraic and dynamical properties of these subshifts and recall known results regarding ...
Extended symmetry groups of multidimensional subshifts with hierarchical structure
(American Institute of Mathematical Sciences, 2020)
The centralizer (automorphism group) and normalizer (extended symmetry group) of the shift action
inside the group of self-homeomorphisms are studied, in the context of certain Z(d) subshifts with a
hierarchical supertile ...
Radial symmetry of ground states for a regional fractional nonlinear schrödinger equation
(2014)
The aim of this paper is to study radial symmetry properties for ground state solutions of elliptic equations involving a regional fractional Laplacian, namely
(-[delta])[alfa][ro][ípsilon]+u = f(u)in Rn, for [alfa] ...
Index of symmetry and topological classification of asymmetric normed spaces.
(Rocky MT Math Consortiumariz State Univ, Dept Math, 2020)
Let X, Y be asymmetric normed spaces and Lc(X, Y ) the
convex cone of all linear continuous operators from X to Y . It is known
that in general, Lc(X, Y ) is not a vector space. The aim of this note is to
give, using ...
On the integration of fields and quanta in time dependent backgrounds
(Springer, 2014)
Field theories with global continuous symmetries may admit configurations in
which time translation invariance is broken by the movement of homogeneous background
fields evolving along the flat directions implied by the ...
Qualitative properties of positive solutions for mixed integro-differential equations
(American Institute of Mathematical Sciences, 2019)
This paper is concerned with the qualitative properties of the solutions of mixed integro-differential equation (equation presented) with N ≥ 1, M ≥ 1 and ϵ 2 (0; 1). We study decay and symmetry properties of the solutions ...
Breaking symmetries to rescue sum of squares in the case of makespan scheduling
(Springer, 2020)
The sum of squares (SoS) hierarchy gives an automatized technique to create a family of increasingly tight convex relaxations for binary programs. There are several problems for which a constant number of rounds of this ...
Radial and cylindrical symmetry of solutions to the Cahn-Hilliard equation
(Springer Heidelberg, 2020)
The paper is devoted to the classification of entire solutions to the Cahn–Hilliard equation
−u = u −u3 −δ in RN , with particular interest in those solutions whose nodal set is either
bounded or contained in a cylinder. ...
Symmetry and thermodynamics of tellurium vacancies in cadmium telluride
(Elsevier B.V., 2019)
The equilibrium geometries and thermodynamic properties of anion vacancies in cadmium telluride, as predicted by density functional theory, are revisited using semilocal and hybrid density functionals. We find that stable ...
